Accessing IMS databases with CICS

CICS® application programs can access DL/I databases through DBCTL. This means that DBCTL satisfies CICS DL/I requests by means of the CICS-DBCTL interface.

CICS/ESA and CICS Transaction Server for z/OS® provide support for IMS DBCTL.

Installing data sharing with CICS: CICS users can optionally use the IMS data sharing facility. The Internal Resource Lock Manager (IRLM) is mandatory for block-level data sharing, but not for database-level sharing.
Installing CICS for use with IMS intersystem communication: Information about defining CICS as an Intersystem Communication node and defining CICS tables to be compatible with IMS in an Intersystem Communication network is provided in Intersystem Communication (ISC).
